I had to rebuild one of these in a 1910 Chick. Fortunately, only stripped screws and a broken dowel. For the metal parts, I think you'd have to see someone with a machine shop. It's great that Chickering was so inventive. Some of their ideas are really good--like the large, easily removable wing-nut bolts holding the cheek blocks from underneath their grands--and have been copied by other companies. But other of their ideas just made for non-standard stuff that didn't really work any better than what everyone else was doing. IMHO their upright trap designs are in the latter category.

I have a client with a Chickering Upright, the 67BB model, that uses an oddball leaf spring design on the pedals. Each pedal has two leaf springs, @51/4" long, with two screw holes at the butt end and a screw hole at the curved tip through which it is mounted to the pedal lever. The levers themselves run diagonally from the pedals up to the lift rods coming down from the action. Schaff does not carry anything like these. Anyone have an idea of where to find replacements, or have you had replacements made? I can't see how they could be converted without reengineering the whole trap assembly. Thanks forl your help.
